Habitat evolution of a peat swamp forest and belowground carbon sequestration during the Holocene along the coastal lowland in Central Sumatra, Indonesia

The tropical peat swamp forest in Malaysia has reduced significantly due to increasing pressure for development and demand for agricultural land. Pekan peat swamp forest is part of the 200,000 hectares of peat swamp forest located in Pahang, Peninsular Malaysia. While more extensive studies were done on flora and fauna, the study on microbial diversity in this habitat is very limited. The highly acidic environment, low concentrations of nutrients and anoxic condition of the peat are among challenges that hampered the cultivation of microorganism from this environment. In this study two types of agar-based medium, M1 minimal medium (M1) and peat water medium (PW) supplemented with glucose, methanol and lignin were used to isolate bacteria from the peat sediment. In comparison to M1, the use of PW has resulted with higher number of isolates with different morphologies. The PW mainly contains the acidic peat water that was collected from the sampling location. Based on the growth on medium supplemented with lignin, selected isolates were identified using 16s rDNA sequencing. At least three of the isolates showed sequence similarity to Burkholderia sp., which is one of the common species, studied on their ligninase-producing abilities. The results from this study serve as the preliminary data for further work on growth characteristics and enzymatic potential of isolates from acidic peat swamp soil.

This study focuses on factors controlling CO2and CH4emission in a peat swamp forest related to water table and peat characteristics such as peat depth, C-organic, pH, ash content and N-total. This study was conducted in the dry season at a Merang peat swamp forest that has degraded due to logging activities, forest fires and canal opening. Emission of CO2and CH4was measured by using a closed chamber made by PVC material (60 cm x 60 cm x 40 cm). This close chamber was completed with a fan inside the chamber to stir the gas, a thermometer inside the chamber to measure the gas temperature and a syringe to sample gas. This study has shown that the highest CO2emission is at an average of 438.93 mg/m2/hr occurring in land cover type (1) ferns and grasses (open burned area) and the lowest is at average of 44.45 mg/m2/hr in thegelamandbelidang-dominated land. The emission of CH4is very low between 0.0018 to 0.0069 mg/m2/hr. the main controlling factor on CO2and CH4emission is concluded to be the water table. The emission of CO2will be greater if water table, pH and C-organic increase.

Tanjungpura University Forest for Special Purpose located in three districts Landak Regency, Mempawah Regency and Kubu Raya Regency. Has the potential to use and process non-timber forest products. The diversity of macroscopic fungi is not yet known as one of the potential natural biological resources of significant value. So that a mushroom inventory must be carried out to identify and assess the diversity of macroscopic fungi. The method used is the survey method. Data retrieval uses a double plot sampling technique. The size of each observation plot is 5 m × 5 m as the initial reference, four plots in the peat swamp forest area with open canopy cover conditions and also four observation plots in peat swamp forest areas with canopy cover conditions are still closed. Placement of research plots in both areas was carried out purposively in locations where there were many types of macroscopic fungi. The results showed that the types of macroscopic fungi found at the study site were 24 species. 24 species were divided into 594 individuals belonging to 23 genera and 9 families. Macroscopic fungi found in open canopy cover were found in 17 species, while in closed canopy cover there were 13 species. In both types of conditions the place to grow has the same 6 types of fungi. The degree of diversity of macroscopic fungi in various conditions the peat swamp in Tanjungpura University Forest for Special Purpose is low.Keyword: Macroscopic fungi, peat swamp forest, Tanjungpura University Forest for Special Purpose.

Physic Analysis

Until now the raw material of wood especially Gelam (Melaleuca cajuputi) for supporting the construction of housing and other infrastructures is increasingly demand in Indonesia. On the Island of Borneo that partly consists of peat swamps needs Gelam very large and continuous, particularly for residential development. Ecological aspects are very important for supporting the silvicultural strategies. The aim of this study is to analyze ecological aspects which are very influence especially physical and chemical soil properties and microclimate as well. The utilization of study is to determine the silvicultural strategies for continuing production and conservation of Gelam in the future. The method was used a field survey around Gelam forest and did collecting samples and measuring there. The results showed in South Borneo the potency of Gelam is only 2,9-7,1 m3/ha and decreasing yearly. Normally Gelam with a diameter <4 cm have been cut down, as well as > 30 cm. Gelam can grow on the peat swamp forest where the soil was low pH 3.5-3.9. Most of pH of soil in these areas was influenced by phyrite (FeS2 of 0.4-2.2% and highest of Fe 90-302 ppm. C organic in the soil was included low-moderate 5.5-10.0%. Result of soil physic analysis showed composition of sand, dust, and clay of 9 : 54 : 57 % respectively. Temperature and humidity around peat swamp forest areas where was found Gelam were 31-33oC and 63-73% respectively. Most of areas around Gelam were grown Gelam Tikus (Syzygium inophylla) and some kind of shrubs.Key words: Gelam, potency, ecological aspects, silviculture

Sampling Plot

Ecological and potential study of ramin was conducted in September 2002. Sampling plot of 20 meters x 1,000 meters with distance between plots was 1 km with total transect of three. Observation within the transect were on stage of tree, pole, sapling and seedling measured. Predominant species were Gluta renghas, Kingiodendron sp., and Shorea spp. The tree stages of ramin was 1.48 tree/ha, poles stage 33.75 individual/ ha, sapling stage 125 individual/ha, and seedling stage 468.75 individual/ha. Ramin was closely related to Kingiodendron sp., G. renghas, and Mezzettia parviflora. However, this species did not associate with Litsea sp., Dryobalanops abnormis, and Canarium caudatum. The habitat of ramin was peat swamp forest with the depth of more than 3 m and influenced by tide but the water remain unsalted. AbstrakUntuk mengetahui ekologi dan potensi jenis ramin (G. bancanus) di habitat alamnya dilakukan penelitian pada bulan September 2002. Penelitian menggunakan satuan contoh berupa jalur dengan lebar 20 m, panjang 1.000 m dengan jumlah pengamatan 3 jalur dan jarak antar jalur 1 km. Pada jalur ini dilakukan pengukuran semai, pancang, tiang, dan pohon. Jenis tumbuhan yang mendominasi tegakan di kelompok hutan Sungai Tuan-Sungai Suruk adalah Gluta renghas (rengas), Kingiodendron sp. (sempetir), dan Shorea spp. (meranti). Ramin memiliki kelimpahan 1,48 pohon/ha untuk tingkat pohon, 33,75 individu/ha untuk tingkat tiang, 125 individu/ha untuk tingkat pancang, dan 468,75 individu/ha untuk tingkat semai. Jenis-jenis yang berasosiasi kuat dengan ramin adalah Kingiodendron sp. (sempetir), Gluta renghas (rengas), dan Mezzettia parviflora (pisang-pisang). Sedangkan jenis yang berasosiasi tidak kuat dengan ramin adalah Litsea sp. (medang), Dryobalanops abnormis (kelansau), dan Canarium caudatum (kenari hutan). Habitat ramin adalah hutan rawa gambut yang umumnya mempunyai kedalaman lebih dari 3 m yang terpengaruh oleh pasang surut tetapi airnya tidak pernah asin.
